摘要： A power transfer system (10) is provided and equipped with a torque transfer coupling (20) which includes a clutch (38) and a ball-screw actuator (90). The ball-screw actuator (90) functions to axially translate an apply plate (76) via a closed hydraulic system to operatively engage the clutch (38) and vary the frictional engagement thereof.

摘要： An electric drive axle (32 - Figure 3) for use in hybrid vehicles has an electric motor (58) driving a compact gearbox (68). The gearbox includes a planetary reduction unit (70) and a differential (72). The planetary reduction unit has a sun gear (74) driven by the electric motor, and compound planet gears (80) supported from a planet carrier which have a first gear segment (88) meshed with the sun gear and a first ring gear (76) and a second gear segment (90) meshed with a second ring gear (78). The second ring gear drives the differential for transferring power to a pair of output shafts (110 and 118) adapted for connection to one set of wheels. The electric motor and gearbox are mounted in a common housing assembly (50) to provide a compact drive axle assembly.
